Swap and Stake Combo Executor

WHAT IT DOES

The Swap and Stake Combo Executor enables users to swap tokens and immediately stake the output in a single atomic transaction. This combination is essential for users who want to acquire staking positions efficiently, avoiding the need to execute multiple transactions and paying gas twice. By combining swap and stake operations, users can capture yield opportunities quickly and reduce transaction costs. This tool provides a streamlined interface to execute swap and stake combos with configurable amounts, slippage protection, and staking parameters.

The tool reads token balances, current prices, DEX protocol states, staking protocol states, swap parameters, stake parameters, staking position, and approval status. It supports executing a swap from a source token to a target token, followed immediately by staking all or part of the swapped tokens in a staking contract. The tool handles the necessary approvals for both the DEX router and the staking contract, and executes both operations in a single atomic transaction.

HOW TO USE

1. Connect your wallet using the Connect button. The tool automatically detects your connected address and network.

2. Select the network where your tokens, DEX, and staking contract are located using the network dropdown.

3. Enter the source token address, target token address, and the swap amount.

4. Enter the DEX router address and the staking contract address.

5. Enter the stake amount (0 for all) and configure your slippage tolerance percentage.

6. Click "Preview combo" to verify the swap and stake parameters.

7. Review the combo details in the preview panel including source token, target token, swap amount, router, staking contract, and stake amount.

8. Click "Execute Swap & Stake" to submit the combo transaction through your wallet.

9. The tool will handle token approvals (if required) and execute both operations.

TECHNICAL MECHANISM

The tool interacts with the DEX router's swap function and the staking contract's stake function, executing them sequentially within a single transaction. First, it verifies the user's balance of the source token and approves the DEX router to spend the required amount. The swap function exchanges the source token for the target token at the current market rate with slippage protection. Once the swap is complete, the tool approves the staking contract to spend the swapped tokens (if required). The stake function then deposits the specified amount into the staking contract, recording the user's staking position. The entire sequence is atomic—if either operation fails, the entire transaction reverts, ensuring no partial execution. The combo history records the transaction hash and results.

WHAT IT CANNOT SEE

This tool cannot verify that the price feed is accurate or reliable; it relies on the DEX's on-chain pricing. It cannot detect if the oracle has been compromised or manipulated. It cannot ensure that swap and stake combo will execute at the optimal price due to slippage, market volatility, and block timing. It cannot guarantee that staking will succeed if the staking protocol is paused or frozen. It cannot verify that the DEX or staking contracts have not been upgraded or modified. It cannot detect if the combo path is optimal or if the transaction is being front-run by malicious actors. It cannot recover funds if execution fails due to contract bugs, insufficient approvals, out-of-gas errors, or blockchain reorgs. It cannot verify that the staking token is legitimate or not. It cannot predict market movements, price gaps, or flash crashes that may affect combo execution. It cannot guarantee execution during extreme network congestion, high gas prices, or volatile market conditions. It cannot detect if underlying DEX or staking protocols have been compromised. It cannot prevent the user from canceling or modifying combo parameters through other interfaces. It cannot ensure that staking yields are accurate or sustainable. It cannot guarantee that the staked position will be accessible or earn the expected rewards.

PLEASE NOTE

This tool is designed for EVM-compatible blockchains (Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, Avalanche, Fantom, and others). It requires an active wallet connection and sufficient native currency for gas fees. Always verify the token addresses, router address, staking contract address, and combo parameters before executing. The stake amount of 0 stakes all swapped tokens. The tool is provided as-is with no warranty; users assume full responsibility for their transactions and should exercise caution when executing swap and stake combos. For mainnet usage, ensure the DEX router and staking contract have been audited and you understand the risks of staking including impermanent loss, yield variability, gas costs, and smart contract risks.
